Abstract: Isolation and purification of polyisocyanates containing a biuret group, more particularly of those prepared from an aliphatic, cycloaliphatic or arylaliphatic diisocyanate and a biuretising agent.   It consists more particularly in treating the crude polyisocyanate containing a biuret group with an inert gas in the liquid or supercritical state. A polyisocyanate containing a biuret group containing a very small quantity of free monomeric diisocyanate is thus obtained.

Abstract: A liquid metal electromagnetic flow control device (40) for controlling liquid metal flow (C) through a nozzle orifice (44) includes an electromagnetic coil (46) disposed adjacent the nozzle (42) and surrounding the orifice (44) therein, and a nonconductive structure (48) disposed along a portion of the coil (46), occupying an axial portion of the nozzle orifice (44) and leaving an adjacent portion of the nozzle orifice unoccupied. The coil (46) is operable to produce a magnetic field (  ) being axially directed and eddy currents ( ) being azimuthally directed within the nozzle orifice (44) and the liquid metal (C) flowing therethrough. The structure (48) defines eddy current flow regions and eddy current nonflow regions through the orifice (44), the latter being positioned relative to said eddy current flow regions thereof so as to substantially block production of eddy currents (  ) in the liquid metal (C) as the metal flows through the eddy current nonflow regions. Such blockage reshapes the magnetic field (  ) within the orifice (44) at a region of transition (61) between the eddy current flow and nonflow portions of the orifice (44) to have a radially directed component (  ) which produces a substantially axially directed electromagnetic pumping force (  ) in the nozzle (42) which controls the flow of liquid metal (C) therethrough by either impeding or assisting the liquid metal flow.

Abstract: A video signal reproducing apparatus has a filter circuit (31) interposed in a transmission path for a reproduced luminance signal, and the characteristic of the filter circuit (31) desirably includes a band-eliminating characteristic and a comb-filter passband characteristic which can be selectively emphasized. When the reproduced luminance signal has a normal or relatively smaller frequency bandwidth or a relatively small line correlation component, or when the level of the reproduced carrier chrominance signal is high, the band-eliminating characteristic of the filter circuit is emphasized. The foregoing video signal reproducing apparatus is particularly suited for reproducing a color video signal that includes a wide band luminance signal, in which case the comb-filter passband characteristic of the filter circuit is selected or emphasized so as to reduce noise near the color subcarrier frequency, to avoid displacement of a reproduced picture of high definition in the vertical direction and also to avoid interference caused by the vertical non-correlation component of a color picture.
